Frost protection function
The burner is switched ON when the boiler water temperature
reaches 5 °C and will be switched OFF again, when the boiler
water temperature reaches 40 °C.
The circulation pump will be switched ON simultaneously with the
burner and switched OFF after a delay.
To protect the system against frost, the circulation pump can be
started at certain intervals (up to 24 times per day) for periods of
approx. 10 minutes.
